i got a p0304 code and changed the spark plugs, then after a month or so it came back. do i change the coilover now? and how do you tell which one is the number 4 cylinder?

Coilover = coilpack you mean ? No... How many miles are on the car ?

Switch the coil packs on 4 and 2 and see if your misfire follows the coil pack, or if it stays on cylinder 4.

If it follows the coil pack, then replace it.

Also, remember after you unplug the coil packs, the one with the BLACK connector goes in BACK. Black in back (remember that still from my TGV delete adventures).

If your misfire does not follow your coilpack, and stays in cylinder 4, then you might have a bad fuel injector.
